Offset error on Aquilion Multi
March 17, 2020 10:43
Hi guys, I have an issue on a CT Toshiba Aquilion Multi. It began with error of offset acquisition and I found the DAS power supply was turned off. After that I have replaced the power supply but the error comes erratically and random. Sometimes there are other errors like Gantry/Couch in local mode, XC, Mudat Rotsot, artifacts, etc. I have replaced also power supplies of OPCONT pwb, OPCONT and GCIF pwb's, MCONT pwb of DAS, I have cleaned up the slip ring, and the error sometimes happens. Do you guys have any experience like this one? I would appreciate your advice or point of view. Thanks in advance.

Pay attention if error resets by turning off rotary or stationary power bottom sw on gantry base. Doing this, you will know where is the problem. If you have changed optcom and gcif, may be trouble is on mudat.

XC error is fairly generic on these scanners. Could be anything in xray generation. Could be tube, inverter, SRU, HV cable. You need SPAG service software to pull error from XC board should show more information on exactly whats causing the error. Then you can run some SRU tests or view waveforms.. IMES (International Medical Equipment & Service) is very knowledgable about Toshiba CT if you get stuck or dont have SPAG software. SPAG should have came with the system on an install disk.
